FPGA Developer - Remote

Overview

We’re looking for an FPGA Code Engineering Support specialist to help design, implement, and optimize low-level logic on FPGAs used in our high-performance networking systems. You’ll work alongside protocol engineers, network architects, and hardware partners to build and support custom compute and switching infrastructure that powers the DoubleZero network.

In Short

• Develop, simulate, and debug FPGA code (VHDL/Verilog/SystemVerilog) for custom hardware
• Assist with the integration of FPGA logic into broader hardware and networking systems
• Support synthesis, place-and-route, and timing analysis workflows
• Maintain and refactor existing FPGA codebases to improve performance or adapt to new requirements
• Work with hardware and DevOps teams to deploy and monitor FPGA systems in production environments
• Contribute to hardware validation and bring-up of new boards or modules
• Document technical specifications, design notes, and test procedures

Requirements

• Proficiency in VHDL or Verilog and experience with simulation/debugging tools (e.g., ModelSim, Vivado)
• Solid understanding of digital design concepts: state machines, pipelining, timing closure, etc.
• Familiarity with FPGA toolchains from Xilinx
• Hands-on experience working with real-time or latency-sensitive systems
• Comfortable working in a Linux-based development environment and using Git
• Strong communication and collaboration skills, especially across hardware/software interfaces
• Experience implementing mathematical functions and encryption/decryption algorithms in hardware
• Maintain and refactor existing FPGA codebases to improve performance or adapt to new requirements, including experience designing ABIs and command & control interfaces for integration with broader system components
• Exposure to high-speed I/O and interconnect protocols (e.g., PCIe, AXI, 100G/400G Ethernet)

Benefits

• Help design the physical layer powering a decentralized, high-performance internet
• Collaborate with a world-class team building novel infrastructure for web3 and beyond
• Competitive compensation + significant token upside
• Flexible remote work with optional off-sites and team retreats
